Finally got the build tuned. This is my daily driver. I built it to be on the conservative side so i can still run 87 octane and get good gas mileage while driving pretty chill. I get over 40-45mpg with this setup and all i have to do is swap in the larger injectors, hondata, good gas and have the power you see below.

B18b1 82mm x 89mm
P72 GSR 82mm pistons
Stock rods w/ ARP rod bolts
ARP head studs

P72 GSR head ported and polished
Est. Compression 10.5:1
Stock valves, RM Gen II valve springs, Skunk2 titanium retainers
CTR intake and exhaust cams
Skunk2 intake manifold w/ thermal gasket
Omni 68mm throttle body
3” shortram intake w/ velocity stack
DC Sports JDM Header 2.5” collector
2.5” exhaust w/ test pipe
MSD 6A and Blaster coil
OBD II Prelude injectors 290cc
P75 ECU VTEC conversion Hondata S100

not bad for what you where shooting for

 

But the Dyno was done on 91+ Oct. correct?

 

thats a neat build. I love MPG

 

that's awesome man, what's the trick for >40mpg??!

I barely get 38-40mpg if I coast all the time and drive only on the freeway at annoyingly low speed. I've got an ls vtec with gsr cams and an LS tranny in an eg hatch.

 

^^Because I'm jealous! Lol, I get like 18-20mpg from my B20Vtec. Oh well.

 

Thats actually good numbers for a pretty hindered setup..
a better manifold / cams would probbaly break 200whp.

 

Not trying to threadjack but, what kind of mpg do you get from your set up?

 

better cams and exhaust manifold would definitely increase VE and probably allow him to get a few more mpg's out of it.

 

In a eg hatch back, a full tank , gives me about 380miles give or take how i hit vtec / lay into it..

 

I average about 28-32mpg mixed driving with my 2257cc h2b.

 

thanks for the comments guys. Does any one know what the dip right after the vtec switch over at 4500rpms is?

 

what ever it is it doesn't look too bad to me.

 

I thought it had some thing to do with the iab tuning because the stock computer had the same dip and the iabs open around 5500rpm on the gsr.
